| keywords: | improper colouring, unit disk graphs, random unit disk graphs, radio channel assignment |
| abstract: |
For any graph
G
, the
k
-improper chromatic number
χ
is the smallest number of colours used in a colouring
of
k
(G)
G
such that each colour class induces a subgraph of
maximum degree
k
. We investigate the ratio of the
k
-improper chromatic number to the clique number for
unit disk graphs and random unit disk graphs to extend
results of [McRe99, McD03] (where they considered only
proper colouring).

The first source gives you the `gzipped' PostScript, the second the plain PostScript and the third the format for the Adobe accrobat reader. Depending on the installation of your web browser, at least one of these should (after some amount of time) pop up a window for you that shows the full article. If this is not the case, you should contact your system administrator to install your browser correctly.
Due to limitations of your local software, the two formats may show up differently on your screen. If eg you use xpdf to visualize pdf, some of the graphics in the file may not come across. On the other hand, pdf has a capacity of giving links to sections, bibliography and external references that will not appear with PostScript.
